我正在尝试从此处使用 PDColoredProgressView 。它工作正常，但由于某种原因，XCode 认为它没有它并抛出 27 Apple Mach-O Linker (Id) Errors。嗯？任何人都可以解码这个吗？谢谢！

您没有安装核心图形库！添加核心图形库，然后在 PDColoredProgressView.h 添加#import <CoreGraphics/CoreGraphics.h>..

您可能还需要 QuartzCore 来完成您正在做的一些事情！armv7 与它无关我不知道他们为什么把它扔在那里哈哈！

从错误日志中，我相信您缺少项目或库体系结构设置（取决于您使用上述代码的位置）。只需在项目设置中添加 armv6（或其等效架构名称）就可以了。
